Definitions

  • the present invention relates to a method for the optimized determination of machine parameters of an agricultural working machine according to the preamble of claim 1 and an agricultural working machine set up for the optimized determination of machine parameters of the agricultural working machine according to the preamble of claim 19.
  • the focus here is on agricultural machines of all kinds. This applies to tractors, especially tractors, but also harvesting machines such as combine harvesters and forage harvesters.
  • Agricultural machines are adapted to their respective agricultural work tasks using a variety of machine parameters. These machine parameters are, for example, an engine speed, a threshing drum speed, a PTO shaft torque, the gap of a grain cracker, the driving speed and the like.
  • machine parameters are, for example, an engine speed, a threshing drum speed, a PTO shaft torque, the gap of a grain cracker, the driving speed and the like.
  • Various approaches are known for optimizing these machine parameters with regard to specific goals. This optimization can be carried out by the user, who is in particular the driver, himself or in collaboration with a driver assistance system. It can also be fully automated.
  • the user can give the driver assistance system strategy specifications, for example selecting a predefined strategy or weighting several competing optimization goals.
  • the driver assistance system converts these strategy specifications into optimized machine parameters using an application rule, which can be map-based, for example.
  • the EP 2 401 904 A2 describes how, in current agricultural machines, optimized machine parameters are determined from strategy specifications (in particular the selection criteria and optimization criteria there) of a user of the agricultural machine via an application specification (in particular the characteristic curves in combination with the automatic control devices). It is also known that the application regulations can in principle be adapted to the local context, for example, by bringing in an external consultant who brings in expert knowledge.
  • the problem with the successive optimization of the machine parameters with regard to the local context is that it requires a certain amount of time, for example 30 minutes, to determine or parameterize the maps to such an extent that machine parameters optimized for various changes, for example to the field inventory, are then determined from the maps can.
  • the agricultural machine can, for example, run through several non-optimized operating points, i.e. combinations of machine parameters, in order to determine support points of the map or maps.
  • the agricultural machine runs with changing and non-optimal machine parameter settings.
  • the invention is based on the problem of designing and developing the known method in such a way that further optimization is achieved with regard to the stated challenge.
  • optimization routine can be shortened or even eliminated if optimized strategy parameters are used that have already been optimized in a similar local context. These strategy parameters can be used in particular to get closer to the optimized machine parameters for the specific local when starting the optimization routine context to start. This represents a significant improvement compared to previous optimization routines that use the same initial strategy parameters regardless of the local context. This also makes it possible to better adapt agricultural machines that cannot make these adjustments themselves to the local context by analyzing many already optimized machine parameters. For example, you can be given a table with optimized machine parameters depending on sensor measurement data, user specifications and/or other machine parameter settings, from which the driver assistance system then takes the optimized machine parameters.
  • the driver assistance system uses strategy parameters as initial strategy parameters that have already been optimized by at least one agricultural machine in a similar local context.
  • a control arrangement which has a database with stored strategy parameters.
  • the control arrangement selects appropriate strategy parameters from these strategy parameters depending on the respective context and transmits them to the driver assistance system.
  • the agricultural machine carries out an optimization routine while carrying out the agricultural work task and thus successively further optimizes the initial strategy parameters.
  • This optimization routine can be shortened by the improved initial strategy parameters and/or can at least be started with more optimal machine parameters during the optimization routine.
  • the machine parameters optimized in this way are preferably transferred back to the control arrangement.
  • the user also intervenes in the optimization of the agricultural machine and thus acts as a human Sensor and human optimization routine acts.
  • optimized strategy parameters can be determined together, which are also based on the user's expert knowledge. These optimized strategy parameters can also or precisely be transferred to the control arrangement.
  • Claim 5 specifies a preferred embodiment of the strategy and in particular of the application instructions, in which at least one map is used to determine the optimized machine parameters. In the simplest case, these can simply be read from the map depending on the input parameters.
  • the strategy includes a cost function which weights the strategy specifications as part of the application rule.
  • the aim of the cost function can be to minimize predefined costs, whereby the minimum of the cost function indicates where the machine parameters are optimal for the given strategy specifications. An entry or change in the strategy specifications can be reflected in a change in the weights of the cost function.
  • Claim 7 specifies one way in which the optimization routine can be designed. Accordingly, the driver assistance system can approach reference points in the map by actually setting the associated machine parameters on the agricultural machine and measuring the resulting influences on the strategy specifications using the sensor arrangement, directly or indirectly.
  • the coefficients and/or a shift in a map can be determined from the support points. Due to the improved initial strategy parameters, there is in particular the possibility of only moving the map or maps in the optimization routine and making no or only small changes to the coefficients.
  • the optimization routine is dependent on the initial strategy parameters.
  • This embodiment is the subject of claim 8. Accordingly, the support points can be selected depending on the initial strategy parameters and/or the optimization routine can be shortened. This results in an overall more efficient execution of the agricultural work task and higher user acceptance.
  • Claim 9 relates to the preferred embodiment that the initial strategy parameters include optimized machine parameters and these are in particular initially set on the agricultural machine until the optimization routine at least has progressed somewhat. This means that the agricultural work task can be carried out more efficiently at the start.
  • the initial strategy parameters can include strategy specifications and/or initial strategy parameters of the application rule. For example, it can be provided that strategy specifications that were set by other users in similar local contexts are used initially. The user can then change this. Such a setting of the strategy specifications by the user is the subject of claim 11.
  • Claim 12 specifies a preferred embodiment of the application instructions. Accordingly, the interface to the user can be constant in the form of strategy specifications, but “under the hood” it can lead to a different result with the optimized machine parameters. This is a description of the particularly preferred mode of operation of the strategy, in particular the application instructions.
  • Claim 13 specifies a preferred embodiment of the control arrangement. This is therefore located external to the agricultural machine and can be accessed via the Internet.
  • Claims 14 to 17 specify preferred configurations of the local context or contents of the local context data that are used to determine the similarity.
  • the initial strategy parameters can in particular be passed on from day to day on the same agricultural machine. In the simplest case, the agricultural machine starts the next day with the initial strategy parameters that were optimized the day before. However, the time interval can also be a longer period of time, in particular an entire season.
  • Claim 15 relates to the possibility of transferring initial strategy parameters between different agricultural machines in the same field or a field in close proximity.
  • initial strategy parameters are transferred between agricultural machines. This makes sense, for example, if one of the agricultural machines starts carrying out the agricultural work task later or not at all is able to determine optimized strategy parameters. The probability of a similar local context is higher for nearby fields.
  • the similarity of the local contexts can be determined according to claim 16 using a similarity measure that takes particular account of climate zones of the respective local contexts. It has been shown that agricultural machines in different climate zones have differently optimized machine parameters, even with the same strategy specifications, and that in some cases different strategy specifications are used. This influence of the climatic zones is not taken into account in previous driver assistance systems, which always use the same initial strategy parameters, in particular the same initial map. However, the initial optimization of the machine parameters can be improved particularly efficiently using a big data approach. In the control arrangement, strategy specifications for many agricultural machines can be arranged according to climatic zones and, for example, their average values can be used as initial strategy specifications.
  • the climate zones can be divided into similar climate zones according to the Köppen-Geiger classification.
  • the proposed method is particularly advantageous in a combine harvester. It has been shown that the dependence on climatic zones in a combine harvester leads to significantly different optimized machine parameters. This configuration is the subject of claim 18.
  • an agricultural working machine is set up for the optimized setting of machine parameters of the agricultural working machine.
  • driver assistance system is set up to use strategy parameters as initial strategy parameters that have already been optimized by at least one agricultural machine in a similar local context.
  • the proposed solution can be applied to a wide range of agricultural machines 1, in particular to harvesting machines. These include combine harvesters, forage harvesters, tractors, especially tractors, etc.
  • Such agricultural machines 1 are used for a variety of different agricultural work tasks. Shows as an example Fig. 1 a harvest activity.
  • machine parameters are machine parameters in the narrow sense such as the engine speed or a position of a throttle valve. Adjustments for the rear power lift and the like are also included. In principle, however, their setting can be done indirectly by the driver assistance system 2, for example by generating control signals for a dedicated control unit of a work unit and transmitting them to the dedicated control unit.
  • the exemplary embodiment shown in the figures and preferred in this respect relates to a method for the optimized determination of machine parameters of an agricultural machine 1.
  • Optimized machine parameters 3 are therefore neither optimal nor necessarily always more optimal than before. They are merely the result of one Optimization. Also, not all target variables of the optimization can necessarily be detected by sensors, in particular they cannot always be detected directly, but rather can only be derived indirectly.
  • the agricultural machine 1 has a driver assistance system 2 and a sensor arrangement 4. As in Fig. 1 schematically indicated, the agricultural machine 1 carries out an agricultural work task in a local context.
  • the local context refers to all influencing factors that are basically present at the place where the agricultural work task is carried out, i.e. locally, and which influence the result of the agricultural work task.
  • the local context only means that portion of these influencing variables that is also known to the agricultural machine 1, in particular the driver assistance system 2, and/or the control arrangement 5, which is yet to be explained.
  • the influencing variables can be measured, but can also be obtained from a weather service, for example.
  • the local context here and preferably includes the weather and/or the climate and/or a type and/or variety of fruit and/or harvest conditions such as straw or grain moisture and/or selected plant protection measures and/or a degree of ripening and/or a soil condition. Additionally, machine equipment can be taken into account. GPS data can be used to determine the local context.
  • the driver assistance system 2 now determines in a determination routine 6 using a parameterizable strategy 7 optimized machine parameters 3 for the agricultural machine 1 for carrying out the agricultural work task. This process is abstract in Fig. 2 a) shown and will be explained further below.
  • the strategy 7 includes strategy specifications 8, an application regulation 9 and the optimized machine parameters 3.
  • the strategy 7 can be parameterized by strategy parameters 10 to adapt to a local context, as will also be explained.
  • the driver assistance system 2 uses the strategy specifications 8 as input parameters of the application rule 9 in order to obtain the optimized machine parameters 3 to be determined as the initial parameter of application regulation 9.
  • the optimized machine parameters 3 are optimized with regard to the strategy specifications 8.
  • the driver assistance system 2 parameters the strategy 7 with initial strategy parameters at the beginning of carrying out the agricultural work task.
  • the initial strategy parameters can still be adjusted when carrying out the agricultural work task.
  • Strategy specifications 8 can include abstract strategies 7 and/or weightings of quality criteria.
  • the abstract strategies 7 here and preferably include a machine-friendly strategy 7 with low wear on the autonomous agricultural machine 1 and/or an eco mode with low energy consumption but longer working hours and/or rapid processing with higher fuel consumption, and/or a higher harvest quality more time required and/or a high throughput with lower harvest quality.
  • the quality criteria preferably include competing quality criteria for which the user, as in Fig. 2 shown as an example for three quality criteria, a weighting can be set graphically. The graphic display visualizes the competition between the quality criteria. The optimization is therefore a multi-objective optimization.
  • the strategy specifications 8 are specified by the user.
  • each quality criterion is generally defined by an optimization target or the setting of a work process parameter.
  • the term “optimization” can include the maximization or minimization of the respective work process parameter.
  • the term “setting” means that the respective work process parameter should assume a specific value and the driver assistance system 2 optimizes the machine parameters so that this value is assumed, if possible.
  • the quality criteria can preferably be selected from the list including "threshing", “broken grain content”, “separation losses”, “cleaning losses”, “threshing mechanism drive slip”, “fuel consumption”, “throughput”, “cleanliness” and “straw quality".
  • a work process parameter can, for example, be a driving speed or a harvest throughput be. The work process parameters are adjusted through the interaction of machine parameters with the local conditions.
  • driver assistance system 2 uses strategy parameters 10 as initial strategy parameters that have already been optimized by at least one agricultural machine 1 in a similar local context.
  • the initial strategy parameters can be optimized by an agricultural machine 1 or strategy parameters 10 of several agricultural machines 1 can be linked to one another.
  • Initial strategy parameters are strategy parameters 10 that are used at the beginning of the execution of the agricultural work task to parameterize strategy 7.
  • the initial strategy parameters include initial coefficients of characteristic maps 12 of the application specification 9, as will be explained below. These initial coefficients are used to parameterize initial maps 12.
  • the initial maps 12 are used at the beginning of carrying out the agricultural work task. Overall, the term “initial” in this case always refers to the beginning of an agricultural work task.
  • the strategy parameters 10 can include strategy specifications 8, coefficients 11 of maps 12 and the like.
  • a similarity measure can be defined or, as will be explained, climate zones can be used.
  • the optimized machine parameters 3 are set by the driver assistance system 2 on the agricultural machine 1 and used to carry out at least part of the agricultural work task.
  • Fig. 1 shows that here and preferably a control arrangement 5 is provided for distributing optimized initial strategy parameters.
  • This control arrangement 5 can in principle be part of the agricultural machine 1, in particular the driver assistance system 2. Here and preferably it is arranged externally to it.
  • the control arrangement 5 has a database 13 with stored strategy parameters 10 and associated data on local contexts.
  • the database 13 can be part of the control arrangement 5 or arranged externally to it.
  • the stored strategy parameters 10 were successively optimized from initial strategy parameters by driver assistance systems 2 of agricultural machines 1 in optimization routines 14 when carrying out agricultural work tasks in local contexts in order to adapt to the respective local context. This can be historical and/or current data, which in principle can come from nearby or from all over the world.
  • the driver assistance system 2 determines context data of the local context of the agricultural work task, in particular by means of the sensor arrangement 4, and transmits this to the control arrangement 5. Additionally or alternatively, the control arrangement 5 can also determine the context data itself, in particular from GPS data of the agricultural machine 1. The determination can also be limited to pure selection. Here and preferably, however, average values of a large number of initial strategy parameters from similar contexts are formed or these are otherwise linked and transmitted as initial strategy parameters. When averaging, the initial strategy parameters from similar contexts can be weighted, preferably depending on the trustworthiness of the data and/or a similarity index. Additionally or alternatively, several initial strategy parameters, which are particularly far apart and thus potentially form local maxima, can be tried out.
  • control arrangement 5 determines initial strategy parameters adapted to the local context and transmits these to the driver assistance system 2 of the agricultural machine 1.
  • the driver assistance system 2 uses the transmitted initial strategy parameters as initial strategy parameters.
  • the agricultural machine 1 determines sensor data relating to the achievement of the strategy specifications 8 in an optimization routine 14 controlled by the driver assistance system 2 by means of the sensor arrangement 4 during the implementation of the agricultural work task, in particular at the beginning of the implementation of the agricultural work task, and that the driver assistance system 2 successively optimizes the initial strategy parameters in the optimization routine 14 based on the sensor data and thus further optimizes the optimized machine parameters 3.
  • the initial strategy parameters are used as the starting point of the optimization routine 14, whereby better results are achieved at the beginning of the optimization routine 14. It also makes it possible for the optimization routine 14 to be shortened.
  • initial strategy parameters and their use analogous to the use described can be provided in later phases of carrying out the agricultural work task.
  • the agricultural working machine 1 can compare its own performance with the performance of other agricultural working machines 1 and, depending on the performance, again use initial strategy parameters of another agricultural working machine 1.
  • An optimization routine 14 can then optionally be carried out again.
  • initial strategy parameters of other agricultural machines 1 can be used regularly, for example when the local context changes.
  • driver assistance system 2 then transmits the optimized strategy parameters 10 and the context data to the control arrangement 5.
  • the user adjusts at least one, preferably several, of the strategy parameters 10 after and/or during the optimization routine 14, preferably that the driver assistance system 2 transmits the thus jointly optimized strategy parameters 10 and the context data to the control arrangement 5.
  • the user sets here and preferably the strategy specifications 8 and/or optimization criteria. In principle, provision can still be made for him to intervene more deeply in the system and even adjust machine parameters individually.
  • the proposed solution is particularly suitable in the case that the strategy 7 includes at least one map 12, which depicts relationships between the machine parameters and the strategy specifications 8, in particular in the form of mathematical functions.
  • maps 12 are in the Figures 1 and 2 pictured. It is difficult or impossible to depict the functionality of an agricultural machine 1 mathematically precisely in all conceivable operating points and taking all contexts into account. However, it is possible to model some working points and relationships and achieve good optimization results within certain limits.
  • An initial map can be adapted to the local context using supporting points 15 that will be explained later.
  • several maps 12 are provided, which, for example, represent individual work units of the agricultural machine 1.
  • the driver assistance system 2 determines the optimized machine parameters 3 based on the strategy specifications 8 from the map 12 or the maps 12. In particular, the driver assistance system 2 simply reads the optimized machine parameters 3 from the maps 12.
  • the map 12 or the maps 12 has or have coefficients 11 that parameterize the mathematical functions. These are determined or corrected here and preferably from the support points 15.
  • a tabular representation of empirically determined relationships can also be provided, which replaces the maps 12. Especially in this case it is advantageous if the tabular illustration is displayed is adapted to the context.
  • the tabular representation is not necessarily further optimized in an optimization routine 14.
  • the strategy 7 includes a cost function 16.
